How long would it take to poke the moon?
It takes about 3 days for a spacecraft to reach the Moon. During that time a spacecraft travels at least 240,000 miles (386,400 kilometers) which is the distance between Earth and the Moon. The specific distance depends on the specific path chosen.
What happens if you move faster than light?
Time Travel Special relativity states that nothing can go faster than the speed of light. If something were to exceed this limit, it would move backward in time, according to the theory. If the neutrinos really are traveling faster than light, then they should be time travelers.
Does Force travel faster than light?
The effects of force fields do not travel faster than light; nothing in the current model of physics travels faster than light. However, some do travel at the speed of light.
Why can’t we beat speed of light?
The speed of light in a vacuum is an absolute cosmic speed limit. According to the laws of physics, as we approach light speed, we have to provide more and more energy to make an object move. In order to reach the speed of light, you’d need an infinite amount of energy, and that’s impossible!
Why does the top string deflect more than the bottom string?
In this case the system does experience the force conditions the professor drew on the board. The tension in the top string is greater than the bottom by a magnitude of the block’s weight, therefore the top string deflects further than the bottom until the point of maximum deflection where failure occurs in the top string.
How many strings of lights can I string together?
A typical string of 100 lights is ~ 40 watts, so I’m guessing you could string up to 5-6 of these together, but definitely follow the recommendation on the package. If you can wire one string to the AC power then you can wire two strings in parallel to the same AC mains providing you don’t exceed the 15A.
How does the length of the string affect the frequency?
For example, if the string has two extra nodes, the shortest section of the string has a length of L/3. Since the frequency of vibration is inversely proportional to the length of the string, a string with a length of L/3 will have a frequency of 3x(fundamental frequency), or 3f.
What happens if you connect 8 strands of lights together?
If you have eight strands connected “in series”, the wires in the first couple of strands will likely overheat and melt the insulation. Very definitely, Peter’s answer is correct, if you string all these lights together, you’ll be putting yourself at a risk for an electrical fire.
